|0.4 mg/mL of mouse anti-VNN2 monoclonal antibody. Dilute to a working concentration of 2.0 μg/mL in CBS before coating.|
|0.5 mg/mL rabbit anti-VNN2 polyclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.|
|Each vial contains 200 ng of recombinant VNN2. Reconstitute standard powder with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 10000 pg/mL is recommended.|
|The minimum detectable dose of Human VNN2 / Vanin-2 was determined to be approximately 156.25 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.|
|The Human VNN2 / Vanin-2 ELISA Pair Set is for the quantitative determination of Human VNN2 / Vanin-2.|
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for VNN2 / Vanin-2 coated on a 96-well plate. Standards and samples are added to the wells, and any VNN2 / Vanin-2 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-VNN2 / Vanin-2 polyclonal antibody is then added, producing an antibody-antigen-antibody “sandwich”. The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of VNN2 / Vanin-2 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.

Vascular non-inflammatory molecule 2, also known as glycosyl-phosphatidyl inositol-anchored protein GPI-80, Vanin-2, Protein FOAP-4 and VNN2, is a cell membrane protein which belongs to the CN hydrolase family and Vanin subfamily. VNN2 is widely expressed with higher expression in spleen and blood. VNN2 is a member of the vanin family of proteins which share extensive sequence similarity with each other, and also with biotinidase. The family includes secreted and membrane-associated proteins, a few of which have been reported to participate in hematopoietic cell trafficking. No biotinidase activity has been demonstrated for any of the vanin proteins, however, they possess pantetheinase activity, which may play a role in oxidative-stress response. VNN2 is an amidohydrolase that hydrolyzes specifically one of the carboamide linkages in D-pantetheine thus recycling pantothenic acid (vitamin B5) and releasing cysteamine. It is involved in the thymus homing of bone marrow cells. VNN2 plays a role in transendothelial migration of neutrophils and may regulate beta-2 integrin-mediated cell adhesion, migration and motility of neutrophil.
